Worldwide, 1 in 12 couples experience difficulty in getting pregnant and seek the help of assisted reproductive technologies ART such as in vitro fertilization IVF-egg is fertilized by sperm outside the body , ovarian stimulation medications are used to stimulate egg development and intra-cytoplasmic injection ICSI-single sperm is injected directly into the egg. Regardless of the ART procedure being performed, the newly fertilized embryo must still implant into the mothers endometrium inner lining of uterus. Intrauterine infusion of hCG prior to embryo transfer has recently been shown to increase pregnancy rates but the cellular mechanism for this increase is unknown. Successful implantation requires the newly fertilized embryo and the endometrium develop in a synchronized manner. This coordinated development is accomplished, in part, by proteins secreted by the embryo which circulate throughout the maternal bloodstream and alert the maternal body organs i. One of the earliest of these secreted proteins is human chorionic gonadotropin hCG , which is the molecule detected in over-the-counter pregnancy tests. From previous studies, we know that hCG production by the embryo alerts the ovary to continue producing progesterone, a hormone required for pregnancy.

Published online January 1, Endometrial pattern and thickness were observed in those patients receiving infertility work up from April, 1 f94 to July, at Seoul National University Hospital. The study group was patients with normal regular menstrual cycles. Among them, 44 patients received endometrial biopsy, and the date of endometrium was compared with the observed endometrial pattern and thickness.
Dating of secretory endometrium
Metrics details. Chronic endometritis CE is a continuous inflammation of uterine endometrium, and it is usually symptomless. As CE has been thought not to affect the reproductive status and general health of affected women, its significance has not been explored. However, recent studies have shown that CE is related with repeated implantation failures after in vitro fertilization-embryo transfer, unexplained infertility, and recurrent miscarriages.
As decidua differentiates to support the implantation process and maintains the pregnancy, we hypothesized that CE may influence the process of decidualization. Seventeen patients were employed in the experiment involving culture of endometrial stromal cells ESCs.

Engman is a fellow in reproductive endocrinology and infertility, University of Connecticut School of Medicine, Farmington, Conn. Disagreement about the cause, true incidence, and diagnostic criteria of this condition makes evaluation and management difficult. Here, 2 physicians dissect the data and offer an algorithm of assessment and treatment.
Despite scanty and controversial supporting evidence, evaluation of patients with infertility or recurrent pregnancy loss for possible luteal phase deficiency LPD is firmly established in clinical practice. Although observational and retrospective studies have reported a higher incidence of LPD in women with infertility and recurrent pregnancy losses than in fertile controls, 1 – 4 no prospective study has confirmed these findings.
Endometrium is the inner most part of uterus its structure and thickness vary according to the different phase of menstrual cycle there are three.
Compromised receptivity of the endometrium is a major cause of unexplained infertility, implantation failure and subclinical pregnancy loss. Nine proteins were found to be differentially expressed between early- and mid- secretory phases of endometrium of infertile women. The expression of Ras-related protein Rap-1b, Protein disulfide isomerase A3, Apolipoprotein-A1 Apo-A1 , Cofilin-1 and RAN GTP-binding nuclear protein Ran were found to be significantly increased, whereas, Tubulin polymerization promoting protein family member 3, Superoxide dismutase [Cu-Zn], Sorcin, and Proteasome subunit alpha type-5 were significantly decreased in mid- secretory phase endometrium of infertile women as compared to early-secretory phase endometrium of infertile women.
Validation of 4 proteins viz. Sorcin, Cofilin-1, Apo-A1 and Ran were performed in separate endometrial biopsy samples from infertile women. The up-regulated expression of Sorcin and down-regulated expression of Cofilin-1 and Apolipoprotein-A1, were observed in mid-secretory phase as compared to early-secretory phase in case of fertile women.

Endometrium: Secretory phase
Chapter 8 Pathology of Reproductive Endocrine Disorders. An appreciation of the relationship between form and function is important for understanding of female reproduction. An awareness of histologic changes associated with both the normal ovulatory cycle and reproductive diseases allows the physician a better understanding of pathophysiology and potential treatment.
This chapter begins with an examination of the histologic changes in the endometrium associated with a normal ovulatory cycle. This is followed by an illustrated survey of common gynecologic diseases of the reproductive organs that are most likely to present to the reproductive surgeon. The endometrium is functionally divided into two layers: the basalis and the functionalis.

Furthermore, a continuum does between disordered proliferative endometrium and simple hyperplasia. In complex hyperplasia, there does an increase in the gland to stroma ratio with glandular crowding. The glands are often closely packed, although some stroma usually remains between individual glands.
The recurrent miscarriage group showed reduced levels of four mucin-related secretory epitopes, and greater nological dating of the endometrium has been.
Patients and Methods: A novel method was used for endometrial dating, with parameters including menstrual cycle days, Noyes histological criteria, along with immunohistochemical expression pattern of estrogen and progesterone receptors and proliferation marker Ki Results: Endometrial maturation varied individually, occurring 1. Comparison of histological maturation with clinical days after ovulation showed a delay of about 2 days.
Conclusion: Endometrial maturation requires 8 days, rather than the expected 6 days, to reach the histological mid-secretory phase. This is not a delay and is also seen in fertile patients. The new analysis method used is superior to that using Noyes criteria alone and provides a better basis for determining conditions for optimal timing of embryo transfers. The endometrium is one of the major factors involved in embryo implantation.
However, the process involved and the underlying molecular mechanisms that enable the endometrium to enter the receptive phase are still not fully clear. Many researchers have explored various methods for investigating endometrial maturation during the menstrual cycle.
Endometrial thickness is a commonly measured parameter on routine gynecological ultrasound and MRI. The appearance, as well as the thickness of the endometrium, will depend on whether the patient is of reproductive age or postmenopausal and, if of reproductive age, at what point in the menstrual cycle they are examined. The endometrium should be measured in the long axis or sagittal plane, ideally on transvaginal scanning, with the entirety of the endometrial lining through to the endocervical canal in view.
Care should be taken not to include hypoechoic myometrium or intrauterine fluid in this measurement. The normal endometrium changes in appearance as well as in thickness throughout the menstrual cycle:.
